ERASTUS HAMILTON, OF CHICAGO, ILLINOIS.

VENTILA'IOR.

Specification of Letters Patent.

Application filed June 30, 1911.

To all whom it may concern:

Be it known that I, ERASTUS HAMILTON, a citizen of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Ventilators, of which the following is a complete specification.

The main objects of this invention are to provide an improved ventilator adapted for use in rooms in private dwellings, hotels, public halls, public conveyances, etc, where the air is liable to become fouled by the presence of large numbers of people; to provide a ventilator adapted to keep the air in good circulation; to provide a ventilator adapted to perfume or disinfect the air of the room or eompartment'being venti: lated; to provide a ventilator adapted to be operated by Water power, and in which the water comes in contact with the air or fan v chamber and acts to cool the air; and to provide a very strong and durable ventilator of light weight adapted to be noiseless in its operation. Y

A specific embodiment of the invention is illustrated in the accompanying drawings, in which:

Figure 1 is a vertical, central .section of a ventilator embodied in this invention. Fig. 2 is a section taken on line 22 of Fig. 1. Fig. 3 is a section taken on line 33 of Fig. 1. Fig. 4 is a section taken on line H of Fig. 1. 5 is a section taken on line 5-5 of Fig. 2.

In the construction shown, the receptacle 1, which may be constructed of sheet metal or of any other desired material. is preferably cylindrical in form, and the top or cover 2, which is rigidly secured thereon, is provided with an aperture 3 which is out of axial alinement with the body of the receptacle.

At one side of the receptacle, and opening tangentially therefrom, is the air outlet spout 4 from which the air is delivered from the ventilator to the room being ventilated. Said spout is preferably nearer to the to of the receptacle than to the bottom thereo and opens'from the side of the receptacle near to the aperture 3.

Supported on brackets 5 on the inner side of the receptacle, and just above the spout 4, is a screen -6 adapted to support a receptacle 7 containing a disinfectant or perfume. The receptacle 7 as herein show-nis an absorbent material saturated with the disinfectant or perfume, though a dish may be employed if desired.

An adjustable inlet sleeve or pipe section 8 fits tightly but removably in the aperture 3 and projects downwardly into close proximity to the receptacle 7 A deflector 9 is rigidly secured to the inner side and top of the receptacle at a point immediately above the outer end of the opening into the pipe 4 and acts to deflect the air from the upper part of the receptacle down into the fan chamber beneath the screen.

An inlet pipe 10 for the water or other motive fluid extends through the side of the receptacle, near the bottom thereof, to the center of the receptacle, and is provided on its inner end with a T 11, from the ends of which pipe sections 12 extend outwardly and upwardly. On the upper ends of the sections 12 are caps 13, each having an aperture 1-1 in one side thereof for the escape of the motive fluid. Extending upwardly from the T 11 in axial alinement with the receptacle is a standard 15 having anti-friction thrust bearings 16 and 17 on its upper end, between which bearings is mounted the fan plate 18. Said fan plate is of a diameter to extend to near the walls of the receptacle in a plane immediately below the outlet 4, and a downwardly and inwardly directed ledge 19 is secured to the walls of the receptacle and projects inwardly and downwardly beneath the plate 19. Extending downwardly from the plate 18 is an annular flange 20, concentric with the standard 15, and on the inner side thereof is a plurality of vertically disposed motor vanes or blades 21 which extend radially of the flange. The apertures 14 in the caps 13 are so positioned that the water or other motive fluid escaping therefrom will strike said vanes at nearly right angles and cause the pl: te 18 to rotate on the standard.

An outlet pipe 22 for the water leads from the bottom of the receptacle.

Rigidly secured on the plate 18 and extending upwardly therefrom are the fan blades 23 which radiate from near the axis of the receptacle into close proximity to the walls of the receptacle. Each of said blades has its upper inner corner 24 curved over in the direction of rotation of the blade, thereby making the inner end of the blade concave longitudinally of the-blade on its forward side, so that the blade will act to draw the air through the sleeve 8 ill] into the The outer ends Q5 said blades are curved rearvvardl v to make them ('OIWGX on their torvvard sides to permit the air to easily roll 0d the same into the outlet 4. I

The operation the construction shown is as follows: id/hen the Water or other motive fluid is admitted through the pipe 1Q it escapes from the apertures 14: and strikes the vanes and causes the fan to rotate on the standard 15. As the fan rotates the curved portions 24: the blades 23 dravv air into the receptacle through the sleeve 8, and inasmuch as the sleeve is nearer to the side of the receptacle just beyond or tor arandlp of the outlet 4-, with respect to the travel of the fan, the blades will take in the greatest amount of air While passing that point, and as the air carried around the receptacle by said blades it becomes more or less compressed as reaches said outlet 42, and es car es a the outlet with considerable force. As tl' air enters the receptacle passes over the disinfectant or perfume and absorbs a safiicient qnantity oil the same to keep the room and pure. The 'Water striking against 1 ie plate 18 tends to cool the air in fan chamber so that when the air leaves said chamber it is several degrees cooler than when it enters. lhe flange Z0 and the ledge 19 prevent any of the water from being" thrown into the fan chamber. The air above the screen 6 is caused to rotate in nnison with the air in the fan chamber, and when it reaches the deflector 9 it is defiected down into the chamber.

While but one specific embodiment of the invention has been, herein shown and described it vvill anderstood that man of the details she in may be varied or omitted Without departntg from the scope of the claims,
